You can install cinder-volume on any machine in your openstack setup, however most people would run it on the controller. No cinder components need to be install on the compute nodes.

After installing cinder, you need to configure the cinder driver for your storage box. It will set up iSCSI exports when a user attaches or detaches a block device. These instructions may help: http://docs.openstack.org/trunk/config-reference/content/emc-vnx-direct-driver.html (http://docs.openstack.org/trunk/confi...)

To manage the Brocade, you may need another cinder plugin, see here:
